Google has added semantic time support to the time fencing feature of its Awareness API. Prior to semantic time support, time fencing was limited to absolute/canonical time (e.g. 10:00 AM). Semantic time enables the use of more natural time refererences (e.g. after sunset, the weekend, etc.)
We have covered Algorithms.io before on ProgrammableWeb and it is an exciting API using machine learning algorithms to deliver predictive analytics. It has specialized in classifying streaming data using machine learning. Algorithms.io was acquired in December 2013 by LumenData, and we have an exclusive interview with Algorithms.io co-founder Andy Bartley post the acquisition.
